[2] The capsule, no bigger than a tic-tac, could pose significant health risks if found by someone unaware of its nature. Search teams were organized to scan over a thousand kilometers of highway using advanced detection devices to pick up any radiation signals.

[3] Officials described the task as being like 'hunting for a needle in a haystack.' They launched public advisories explaining the dangers and urged anyone in the Outback not to approach any small metal objects they found, but to report them instead.
